行走江河看中国丨“千里眼”“最强大脑”……智慧防汛守护长江安澜

Core Viewpoint - The article discusses the advancements in flood prevention and management along the Yangtze River, highlighting the integration of cutting-edge technologies such as artificial intelligence, digital twins, and high-performance computing into traditional flood defense systems to enhance forecasting, warning, and inter-departmental collaboration [1][5][8]. Group 1: Technological Advancements - The Yangtze River Water Resources Commission has transitioned from experience-driven to data-intelligent practices in flood prevention, utilizing AI, digital twins, and high-performance computing [1][4]. - The "Thousand-Mile Eye" system provides comprehensive monitoring across the Yangtze River basin, covering an area of 1.8 million square kilometers and generating up to a million data points daily, with a reporting rate of 99.8% within 20 minutes [2][4]. - The "Strongest Brain" employs AI and big data analytics to create a multi-time scale quantitative precipitation forecasting system, achieving a short-term forecasting accuracy of over 90% for the middle and lower reaches of the Yangtze River [5][7]. Group 2: Integrated Monitoring Systems - The "Sky, Earth, Water, and Engineering" integrated monitoring system combines data from 86 radars, meteorological satellites, and approximately 50,000 hydrometeorological stations to facilitate proactive flood management [4][8]. - The system allows for real-time simulation of flood scenarios, enabling decision-makers to visualize potential risks and assess the impact of various flood management strategies [10][11]. Group 3: Decision-Making Support - The "Digital Twin Yangtze" system provides a visual representation of flood management strategies, allowing for real-time simulations and comparisons of different operational plans to identify the optimal approach [8][10]. - The integration of human expertise with machine calculations enhances the accuracy of flood predictions, with nearly 1,000 simulations conducted this year to support flood management efforts [7][10].
